Toden Arakawa Line – a very unique & historic streetcar line in Tokyo downtowns

I used my future plan essay, when I surveyed three apartment buildings in Taito-ku, Arakawa-ku, and Toshima-ku last week. The line is the only streetcar system survived in Tokyo, connecting Waseda (Shinjuku-ku) and Minowabashi (Arakawa-ku). The line has been in operation since 1913, and the neighborhoods and towns along the line still show what Tokyo used to look like in Showa Period (1926-1989). Toden Arakawa Line runs through Shinjuku-ku, Toshima-ku, Kita-ku, and Arakawa-ku, most of these districts being downtown and residential.
